II

Sam watched as Dean rubbed his nose over the side of Cassie's face, moving his fingers carefully as he massaged her feet.

"Are you sure you don't want gatorade?" he insisted. "Or juice? Water?"

He wished he was as relaxed as Dean right now, but his mind was running all over the place. The three of them never really address the natural of their relationship. Maybe to his brother it was just rough sex and polyamory, but Sam knew better.

Even without the names, even without the terms, this was a Dom/sub dynamic, with two Doms, sure, but still a power dynamic, and they needed to work on making it safe and healthy.

"I'm okay," she assured him with a soft smile. "Don't worry, Sam."

He grimaced.

"Baby," he insisted, resting his hand on her ankles, and caressed her skin with this thumb. "We were really rough with you."

That made their girl laugh.

"Sam, I was literally thrown into a wall by monsters more times than I can even count," Cassie pointed out, chuckling a bit, and he could hear how her throat wasn't in its natural state. After being fucked for over an hour, he didn't doubt it would be a bit sore. "I think can handle you being rough with me."

He rolled his eyes.

"It's not the same thing," he insisted. "It's not like you have to just take it, you know? You're not here to be used."

Maybe Sam didn't quite realise his tone of voice was a little too loud or mean, but he regretted the way the words left his mouth the moment they did after seeing Cassandra flinching and pulling herself away from him.

"Sorry," he said quickly. "Sorry, I shouldn't have… I'm sorry."

He rubbed a hand over his face, and looked around the room, looking for where they'd thrown her underwear.

"I was thinking," he told them, though not facing the two. "And I don't think we're doing this dynamic correctly."

"Correctly?" Dean repeated, just as he lifted Cassie's bralette from the top of his pile of books. They'd need a wash from all of the dust.

"Yeah," he confirmed. "I mean, any BDSM relationship needs to have some things established rules and agreements, and communication..."

"Wait, wait up," Dean interrupted him, and Sam turned to look at him after having having finally found her panties. "I don't think this is a BDSM relationship, Sam. We're just… people who like rough sex."

He looked down at Cassandra, and she lifted her hips as Sam slid her underwear up her legs.

"Dean," he looked up at his brother."We're literally her doms."

His brother stared at him, mouth opening and closing, and his hand stopped moving over her head, where he was caressing her hair, and Sam watched as she eyed him attentively, and Dean shot her a look, almost pleading for her help.

"He's not wrong, Dean," she pointed out. "I mean… it's what we do, it's how I see it."

Sam relaxed a bit, though becoming tense all over again.

"I listen to you guys, we have crazy sex, we have a safeword and then we have after care," she listed. "Isn't that what BDSM is?"

Yeah, he was doing her dirty with this one.

"Yes and no," he answered. "It is more complicated than that."

She sat up, looking confused, and Sam carefully buttoned up his shirt over her shirt.

"I actually have been working on a contract for us," he told them.

Dean looked at him as if he was crazy.

"A contract?" he repeated. "Sam we don't need-"

"Just listen to me for five seconds, Dean," he interrupted his brother and caressed Cassandra's skin. "Can we talk about that now?"

"Yeah," she nodded. "I want to learn about this."

"Dean?" he looked up at him.

"Yeah, yeah," he mumbled. "You're already doing it anyway."

Sam rolled his eyes, but stood up, walking to his desk and turning his laptop on, not even having to look around for document after spending such a long time working on it, just accessing it through his desktop.

He glanced at them, and found both his brother and his girlfriend dressed up again, with Dean in his shirt and flannel pants and Cassie back in the pants she'd been wearing before anything, and with the sleeves of the big flannel shirt rolled up over her arms.

"Okay, so," he sat on the armchair in front of the bed. "I have this ready to be edited. It's not final, but it's drafted so we add what we want into it."

Cassie nodded, and picked up the laptop from his hands, and he couldn't help comparing how small it looked in his hand but so normal compared to her size. She was so small compared to him, goodness.

Just the idea almost made him get hard again.

"Can I read it aloud?" she asked.

"Yes, love. Go on," he caressed her knee.

He watched her eyes running over the page,

"The document, dated on the start date," she read out loud. "Is a contract of voluntary and total submission between Samuel and Dean Winchester, the Dominants and Cassandra Riley, the submissive. The follow agreement is valid for one year counting on the started date and will be revised on the starter date of the following year upon its expiration. Cassandra, through signing this contract, is binding herself totally and completely, without limit (except as explicitly defined below), irrevocably to submission to Samuel and Dean."

He watched her reaction, and bit his lower as he watched her face moving slowly from surprise to curiosity, happy with the fact it wasn't fear or anything negative.

It was a good start.

"Total submission?" Dean repeated, looking surprised. "Dramatic much, Sam?"

"I mean," she rose her eyes from the screen. "I do already submit completely when we're doing it, Dean. This is just stating the truth."

He grumbled something, but Sam wasn1t quite paying attention.

"I have more written down," he told her. "Spaces to add our personal information, like aftercare, triggers, kink list…"

She frowned a bit.

"Kink list?" Cassie repeated, looking quite curious.

"Yes," he agreed. "It's not permanent, so it can change even before the contract expires."

His brother snorted.

"So we are group sharing our kinks, Sammy?" he raised an eyebrow at him. "No offence, but I don't want you know what rocks my boat."

Sam rolled his eyes.

"I'm not going to look at it, Dean," he assured him. "It's for Cassie to know. I also have something about the privacy of our relationships, and our negotiation on scenes apart from each other."

"Apart?" she questioned, a little confused.

"Spending time alone," he explained. "And when you want to spend time with just one of us. It's important that we maintain independent healthy relationships so there the poly relationship will also be healthy."

Cassandra nodded, seeming to finally understand.

"That's really smart," she praised him, beaming. "You're very dedicated. Sammy."

He felt his cheeks warming up.

"Thank you, baby."

"And what about me?" Dean protested.

Sam rolled his eyes.

"And that is why we need one-on-one time, Dean," he pointed out. "As not to overwhelm her."

Dean mumbled something, and Cas just leant onto him, kissing his cheek.

"You're a great boyfriend, Dean," she assured him.

His brother smiled, blushing a little bit.

"Yeah, I know," he agreed, though doing the same to her.

"You should work on your list, Dean" he told him. "Turn ons and turn offs, kinks… everything I mentioned."

He rolled his eyes.

"You got me homework?" he asked, annoyed.

"Come on, Dean," Cassie looked over him, soft plump lips curling in a pout. "Do it for me."

Dean groaned.

"Fine," he stood up. "Fine, I'll go do it."

Sam chuckled, and watched as their girlfriend stood on her tiptoes, giving his lip a soft peck.

"Thank you, Dean."

He walked out, still looking a bit annoyed, and Sam moved to sit by her side.

"Do you want to get over the list right now?" he suggested. "And then we can see what we like?"

She confirmed with a soft sound, and he opened the separated document with his list, and watched as she read over the list.

"Degradation, breathplay..." she mumbled. "Size kink, I like size kink, chastity… Chastity belt, Sam?"

Her eyes were wide in curiosity, and Sam just chuckled, blushing a bit.

"Uh… I got in contact with a lot in college," he half-explained in a mumble. "We don't have to do it."

"Good, good," she nodded. "Cause I'm not doing it."

He nodded, trying not to show his disappointment. It wasn't that important – he wanted to experiment, that was it – and he was happy that she felt comfortable enough with him to say what she didn't want.

"Moving on," she moved back to the page.

Cassie snuggled into his chest, continuing to read, and Sam finally relaxed, excited with the little glimpse of the future, kissing her temple.
